I'm not sure what you're looking for here, I did a Google search for SansomSoft and no results were returned, and the suggestion wasn't right.

However, I assume you're looking for something like HTTrack. I had done a portable package of HTTrack a while back, but stopped. I kinda hope to redo it again sometime though. If that is what you're looking for, I don't think I can provide you with any solutions right now.

In future, please search as if that's what you're looking for it has already been suggested (couple weeks ago, too) so just search the forums next time.
